Description

3차원 돔형 터치 패턴을 이용한 터치 스크린Touch screen using 3D domed touch pattern
본 발명은 터치 스크린에 관한 것으로, 보다 상세하게는 3차원 돔형 터치 패턴을 이용한 터치 스크린에 관한 것이다. The present invention relates to a touch screen, and more particularly, to a touch screen using a three-dimensional domed touch pattern.
터치스크린을 화면상의 한 점을 사용자의 손가락으로 누르면, 그 접촉점의 좌표값을 기기로 전달하는 위치 감지기가 내장된 화면을 통칭한다. When a user touches a point on the touch screen with a user's finger, it refers to a screen with a built-in position sensor that transmits the coordinate value of the touch point to the device.
터치스크린 인터페이스는 범용화된 지 오래이고, 앞으로는 웨어러블 디바이스의 개발과 더불어 플렉서블 디스플레이에 대하여 적용 가능한 입체적 형태의 터치 스크린에 대한 수요가 늘어날 것으로 예상된다. Touch screen interfaces have been popular for a long time, and in the future, with the development of wearable devices, demand for three-dimensional touch screens applicable to flexible displays is expected to increase.
특히, 자동차 전장과 같이 디자인 요소가 매우 중요한 고려 대상이 되는 분야에서는, 이미 상당부분 입체적 형태의 터치 스크린에 대한 니즈가 있어 왔다. In particular, there is already a need for a three-dimensional touch screen in a field in which design elements are very important considerations such as automotive electronics.
그러나, 종래 기술에 따른 플렉서블 터치 스크린은 평면형 터치 스크린에 대하여 외력을 가하여 일부 구부리는 방식으로 구현되어 왔는데, 스위치 또는 회전 버튼 등에 적용되는 돔형의 터치 스크린 인터페이스 개발에 있어서 그 성형 과정에 있어 왜곡이 발생하는 문제점이 있다. However, the flexible touch screen according to the prior art has been implemented by partially bending by applying an external force to the flat touch screen. In the development of a dome type touch screen interface applied to a switch or a rotary button, distortion occurs in the molding process. There is a problem.
즉, 일례로 평평한 터치 스크린 필름에 열을 충분히 가한 후, 금형 틀로 누르거나 공기를 불어 팽창을 시킨 후 성형을 하는 종래 기술에 따르면, 필름이 늘어나는 연신에 따라 투과율이 투명 도전성 필름의 투과율이 변할 뿐 아니라 저항값의 변화가 발생하여, 초기 설계 단계에서 기획한 스펙과 상이한 양산이 발생하고, 사용자의 터치 지점을 정확하게 인식하지 못하게 되는 문제점이 있다. That is, according to the prior art, for example, after sufficiently applying heat to the flat touch screen film, pressing the mold or blowing the air to expand the mold, the transmittance of the transparent conductive film changes only as the film is stretched. However, there is a problem that a change in the resistance value occurs, a mass production different from the specification planned in the initial design stage, and the user's touch point is not accurately recognized.
본 발명은 전술한 문제점을 해결하기 위하여 제안된 것으로, 3차원 돔형 터치 패턴을 포함하여, 3차원 돔형 터치스크린을 제작하는 위한 성형 과정에 있어 터치 좌표의 왜곡을 방지하고, 연신에 따른 저항 및 위치의 변화를 방지하는 것이 가능한 3차원 돔형 터치 패턴을 이용한 터치 스크린을 제공하는 데 목적이 있다. The present invention has been proposed to solve the above problems, including a three-dimensional dome-shaped touch pattern, to prevent distortion of the touch coordinates in the molding process for manufacturing a three-dimensional dome-type touch screen, resistance and position according to the stretching It is an object of the present invention to provide a touch screen using a three-dimensional domed touch pattern capable of preventing a change of.
본 발명에 따른 3차원 돔형 터치 패턴을 이용하는 터치 스크린은 터치 센싱 영역의 중심을 기준으로 인가되는 외력에 따른 성형에 의하여 구부러져, 구면 좌표 형태로 배치되는 3차원 돔형 터치 패턴을 포함하고, 3차원 돔형 터치 패턴은 기설정된 형상에 따라 설계되어 평면 터치스크린 필름에 배치되고, 외력에 따른 성형에 의하여 전방향으로 인장되는 센서 채널을 포함하는 것을 특징으로 한다. The touch screen using the 3D domed touch pattern according to the present invention includes a 3D domed touch pattern bent by molding according to an external force applied based on the center of the touch sensing area and arranged in spherical coordinates, and a 3D domed type The touch pattern may be designed according to a predetermined shape and disposed on a flat touch screen film, and include a sensor channel that is tensioned in all directions by molding according to an external force.
본 발명에 따른 3차원 돔형 터치 패턴을 이용한 터치 스크린은 돔형태의 터치 스크린 제작에 있어, 성형 시 그 돔형태의 중심측은 연신이 많이 발생하고, 가장 자리는 연신이 적게 발생하여 좌표축이 왜곡되는 종래 기술에 따른 문제점을 해결하고, 구면 좌표 형태로 센서를 배치하여 성형 후에도 터치 좌표의 왜곡을 최소화하는 것이 가능한 효과가 있다. The touch screen using the three-dimensional dome-shaped touch pattern according to the present invention, in the production of the dome-shaped touch screen, when the center side of the dome-shaped during molding, the stretching occurs a lot, the edge is less stretching occurs the conventional coordinate axis Solving the problem according to the technology, it is possible to minimize the distortion of the touch coordinates after molding by placing the sensor in the form of spherical coordinates.
본 발명에 따르면, 기설정된 형상의 센서 채널을 구비하여 3차원 돔형 터치 스크린 제작을 위한 성형 과정에서 필연적으로 발생하는 연신에 의하여도 저항의 변화 및 위치의 변화를 최소화함으로써, 3차원 돔형 터치 스크린을 이용한 사용자 터치 입력 시 그 터치 지점을 정확하고 신뢰성있게 획득하는 것이 가능한 효과가 있다. According to the present invention, the three-dimensional dome-type touch screen is minimized by minimizing the change of resistance and the change of position by the stretching inevitably generated during the forming process for manufacturing the three-dimensional dome-type touch screen with a sensor channel having a predetermined shape. When using the user touch input, it is possible to obtain the touch point accurately and reliably.

In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase. As used herein, “comprises” and / or “comprising” refers to the presence of one or more other components, steps, operations and / or devices in which the mentioned components, steps, operations and / or devices are described. Or does not exclude addition.
본 발명의 실시예를 설명하기에 앞서, 당업자의 이해를 돕기 위하여 본 발명이 제안된 배경 기술을 먼저 살펴보기로 한다. Prior to describing the embodiments of the present invention, the background technology proposed by the present invention will be described first for better understanding by those skilled in the art.
도 1a 및 도 1b는 종래 기술에 따른 평면 터치 센서의 좌표축 및 이를 이용하여 돔형 터치 스크린을 제작할 시 발생되는 연신 현상을 나타내는 도면이다. 1A and 1B illustrate a coordinate axis of a planar touch sensor according to the related art and a drawing phenomenon generated when a domed touch screen is manufactured using the same.
도 1a에 도시한 바와 같이, 종래 기술에 따른 평면 터치 센서의 좌표축은 직교 방식 채널 형태로서, X축 센서 채널(X axis sensor channel) 및 Y축 센서 채널(Y axis sensor channel)이 배치된다. As shown in FIG. 1A, the coordinate axis of the planar touch sensor according to the related art is in the form of an orthogonal channel, and an X axis sensor channel and a Y axis sensor channel are disposed.
종래 기술에 따른 터치 스크린은 플렉서블 형태로 구현된다 할지라도, 이러한 평면형 터치 스크린을 일부 구부리는 방식을 차용하여 제작되어 왔다. Although the touch screen according to the related art is implemented in a flexible form, the flat screen has been manufactured by borrowing a part of the flat touch screen.
또한 3차원 돔형 터치 스크린은 평평한 터치 스크린 필름에 열을 충분히 가한 후, 금형틀로 이를 누르거나 또는 공기 등으로 불어서 이를 팽창시킴으로써, 3차원 돔형 형상으로 성형하는 방식이 제안되어 왔다. In addition, a three-dimensional dome-type touch screen has been proposed to form a three-dimensional dome shape by applying sufficient heat to the flat touch screen film, pressing it with a mold frame or blowing it with air or the like to expand it.
그러나, 이러한 경우 도 1b에 도시한 바와 같이, 필연적으로 필름이 늘어나는 연신 현상이 발생할 수 밖에 없고, 투명 도전성 필름에 연신이 발생하게 되면 투과율의 변화뿐 아니라 저항값의 변화가 발생하여, 터치 스크린에 대한 초기 설계 스펙과는 다른 경향을 가지게 된다. However, in this case, as shown in FIG. 1B, the stretching phenomenon inevitably inevitably occurs in the film, and when the stretching occurs in the transparent conductive film, not only a change in transmittance but also a change in resistance value occurs, resulting in a touch screen. This tends to be different from the initial design specification.
종래 기술에 따르면 이러한 특성 변화와 더불어, 3차원 돔형 터치 스크린 제작 시 좌표의 축이 변하게 되어(즉, 어긋나게 되어), 사용자 터치를 정확하게 인식하는 것이 불가능하다. According to the related art, in addition to such a characteristic change, the axis of coordinates is changed (that is, displaced) when the three-dimensional domed touch screen is manufactured, so that it is impossible to accurately recognize the user touch.
즉, 도 1a에 도시한 바와 같이 평면 터치에서는 일정하게 유지되는 X축 및 Y축의 위치가 돔형으로 성형을 함에 따라서, 연신에 의하여 좌표 축 및 간격이 틀어지게 된다. That is, as shown in FIG. 1A, as the positions of the X-axis and the Y-axis, which are kept constant in the planar touch, are molded in a dome shape, the coordinate axis and the gap are shifted by stretching.
이러한 경우, 인접하는 센서 채널 간의 상대적인 신호 크기에 따라 사용자의 터치 위치를 계산한다 하더라도, 실제 터치가 이루어진 지점을 정확히 인식하지 못하는 문제점이 있다. In this case, even when the touch position of the user is calculated according to the relative signal magnitude between adjacent sensor channels, there is a problem in that the actual touch point is not accurately recognized.
도 1b에 도시된 바와 같이, 3차원 돔형 터치 스크린은 중앙부가 터치 스크린의 상면으로 볼록하게 돌출되는 형태이므로, 연신은 그 중앙부에서 보다 많이 발생하고, 그 중심을 기준으로 가장 자리로 갈수록 연신이 작게 발생하게 되는 바, 종래 기술에 따른 직교 방식 채널 형태의 경우 이러한 연신에 의한 왜곡을 보정하기에 어려운 문제점이 있다. As shown in FIG. 1B, since the 3D domed touch screen has a shape in which the center portion protrudes convexly to the upper surface of the touch screen, the stretching occurs more at the center portion, and the stretching is smaller toward the edge of the center. In the case of the orthogonal channel type according to the prior art, it is difficult to correct distortion caused by the stretching.
본 발명은 전술한 문제점을 해결하기 위하여 제안된 것으로서, 이하에서는 도 2 내지 도 5에 대한 상세한 설명으로서 본 발명의 바람직한 실시예를 서술하기로 한다. The present invention has been proposed in order to solve the above-described problems, hereinafter will be described a preferred embodiment of the present invention as a detailed description of Figures 2 to 5.
도 2는 본 발명의 실시예에 따른 3차원 돔형 터치패턴을 이용한 터치 스크린에 대한 구면 좌표를 나타내는 도면이다. 2 is a diagram illustrating spherical coordinates of a touch screen using a 3D domed touch pattern according to an exemplary embodiment of the present invention.
도 2에 도시된 바와 같이, 구면 좌표계 (r, θ, φ)의 r은 좌표계 원점으로부터 터치 인식 지점까지의 거리, θ는 z축을 기준으로 한 기울어진 각도, φ는 x, y 평면상에서 어느 쪽으로 기울어졌는지를 나타내는 방위각(azimuth)을 나타낸다. As shown in Fig. 2, r of the spherical coordinate system (r, θ, φ) is the distance from the coordinate system origin to the touch recognition point, θ is the inclination angle with respect to the z axis, φ is on the x, y plane It represents an azimuth indicating whether it is tilted.
본 발명의 실시예에 따르면, 평평한 터치 스크린 필름에 열 성형 등을 통하여 3차원 돔형 터치 스크린을 제작하는 방식에 있어서, 기인지된 성형의 중점 및 그러한 중점을 기준으로 구면 좌표 형태로 센서 채널을 배치함으로써, 성형에 따른 연신이 발생하더라도 저항의 변화 및 위치의 변화를 방지하고, 사용자 터치 지점을 정확히 인식하는 것을 가능하게 한다. According to an embodiment of the present invention, in the method of manufacturing a three-dimensional dome-type touch screen through a thermoforming or the like on a flat touch screen film, the sensor channel is arranged in the form of spherical coordinates based on the known center of the molding and such center By doing so, even if stretching occurs due to molding, it is possible to prevent a change in resistance and a change in position, and to accurately recognize a user touch point.
도 3은 본 발명의 실시예에 따른 θ 패턴을 나타내는 도면이다. 3 is a view showing a θ pattern according to an embodiment of the present invention.
도 3에 도시된 바와 같이, 본 발명의 실시예에 따른 θ 패턴은 사용자 터치를 인식하는 영역에 배치된 센서 채널(110, 120)을 구비하되, 각 센서 채널은 동일한 중심을 기준으로 하는 중심부 및 감지된 터치 지점을 인식하기 위한 연장부를 포함하여 구성된다. As shown in FIG. 3, the θ pattern according to an embodiment of the present invention includes sensor channels 110 and 120 disposed in an area for recognizing a user touch, wherein each sensor channel includes a central portion based on the same center and And an extension for recognizing the detected touch point.
본 발명의 실시예에 따른 θ 패턴(100)은 그 중심에 배치되는 중심 센서 채널(110)의 원형 중심부(111)와, 그 일측으로부터 연장되는 연장부(120)를 포함하며, 그 외곽으로 서로 인접한 센서 채널과 겹쳐지지 않도록 배치된 복수의 C자형 센서 채널(120) 및 그에 연결된 각 연장부(122)를 포함하여 구성된다. The θ pattern 100 according to the embodiment of the present invention includes a circular central portion 111 of the central sensor channel 110 disposed at the center thereof, and an extension portion 120 extending from one side thereof. And a plurality of C-shaped sensor channels 120 and each extension 122 connected thereto arranged so as not to overlap with an adjacent sensor channel.
원형 중심부(111)를 가지는 중심 센서 채널(110) 및 그 외곽에 배치되는 C자형 센서 채널(120)은 전술한 바와 같이 각각의 중심부 및 연장부가 서로 다른 센서 채널과 겹쳐지지 않도록 배치되며, 이러한 θ 패턴은 3차원 돔형 터치 스크린 제작을 위한 성형의 중점이 θ 패턴의 중심과 일치되는 경우, 연신 현상에 의하여도 저항의 변화나 위치의 변화가 적어지게 된다. The center sensor channel 110 having a circular center portion 111 and the C-shaped sensor channel 120 disposed at the outer portion thereof are disposed so that each center portion and the extension portion do not overlap with the other sensor channel as described above. When the pattern is formed at the center of the pattern for forming a three-dimensional dome touch screen coinciding with the center of the θ pattern, the change in resistance and the change in position are reduced by the stretching phenomenon.
도 4는 본 발명의 실시예에 따른 φ 패턴을 나타내는 도면이다. 4 is a view showing a φ pattern according to an embodiment of the present invention.
도 4에 도시된 바와 같이, 본 발명의 실시예에 따른 φ 패턴(200)은 사용자 터치를 인식하는 영역에 대하여, 방사형으로 배치된 복수 개의 센서 채널(210)을 포함하여 형성된다. As illustrated in FIG. 4, the φ pattern 200 according to the exemplary embodiment of the present invention includes a plurality of sensor channels 210 disposed radially with respect to an area for recognizing a user touch.
이 때, 방사형으로 배치된 복수 개의 센서 채널(210)은 부채꼴 형상으로 형성된다. At this time, the plurality of radially disposed sensor channels 210 are formed in a fan shape.
본 발명의 실시예에 따른 φ 패턴(200)은 전술한 방사형으로 배치된 복수의 센서 채널의 중앙의 한점(220)을 기준으로 3차원 돔형 터치 스크린 제작을 위한 외력이 인가되는 경우에, 연신이 발생하는 경우에도 저항의 변화 또는 위치의 변화가 적어지게 되어, 사용자 터치의 지점을 정확히 신뢰성 있게 인식하는 것이 가능하다. Φ pattern 200 according to an embodiment of the present invention, when the external force for manufacturing a three-dimensional dome-type touch screen based on one point 220 of the center of the plurality of sensor channels arranged in the above-described radial, stretching is applied Even when it occurs, the change of resistance or the change of position becomes small, so that it is possible to accurately and reliably recognize the point of the user touch.
전술한 바와 같이, φ 패턴(200)의 경우에도 상호 인접한 센서 채널끼리의 겹쳐짐은 없도록 함은 물론이다. As described above, even in the case of the φ pattern 200, there is no overlap between adjacent sensor channels.
도 5는 본 발명의 다른 실시예에 따른 방사형 패턴을 나타내는 도면이다. 5 is a diagram illustrating a radial pattern according to another exemplary embodiment of the present invention.
본 발명의 다른 실시예에 따른 방사형 패턴(300)은 사용자 터치를 인식하는 영역에 대하여, 방사형으로 배치된 복수 개의 센서 채널을 포함하여 구성되되, 각 센서 채널은 도 5에 도시된 바와 같은 스트립(strip) 형상으로 구현된다. Radial pattern 300 according to another embodiment of the present invention is configured to include a plurality of radially arranged sensor channels for the area for detecting the user touch, each sensor channel is a strip (as shown in Figure 5) strip) shape.
이 때, 각 센서 채널은 그 중심부(310)가 스트립 형상으로 구현되고, 방사형 패턴의 중심으로부터 멀어짐에 따라서, 중심부를 기준으로 양 옆으로 연장되어 트리 형태의 패턴을 형성하는 연장부(311)를 포함한다. At this time, each sensor channel has an extension portion 311 whose center portion 310 is formed in a strip shape and extends to both sides with respect to the center portion to form a tree-shaped pattern as it moves away from the center of the radial pattern. Include.
이 때, 연장부(311)는 도 5에 도시된 바와 같이, 방사형 패턴의 중심으로부터 멀어짐에 따라 그 중심부(310)를 기준으로 양 옆으로 번갈아가며 교차 형성되는 것이 바람직하며, 복수의 센서 채널에 대한 각각의 연장부(311)는 상호 인접한 다른 연장부와 겹쳐지지 않도록 형성된다. In this case, as shown in FIG. 5, as the distance from the center of the radial pattern is alternately formed on both sides with respect to the central portion 310, it is preferable to form a plurality of sensor channels. Each extension 311 for each other is formed so as not to overlap another extension adjacent to each other.
본 발명의 다른 실시예에 따른 방사형 패턴(300)은, 일반적인 방사형의 경우 중앙의 한 점으로부터 멀어질수록 각각의 영역이 외곽으로 갈수록 넓어지는 바, 3차원 돔형 터치 스크린에 대한 가장 자리 영역 중 상이한 영역에 대한 터치 시, 그 실제 터치 지점이 상이하더라도 같은 센서 채널 내에서 인식되어 구별이 어려워 지는 바, 사용자의 터치 신호를 보다 정확한 지점에서 인식할 수 있도록 제안된 트리형-방사형 센서 채널을 포함하여 구성되는 것이다. Radial pattern 300 according to another embodiment of the present invention, in the case of a general radial, each area is wider toward the outside as it moves away from a central point, different from the edge area for the three-dimensional domed touch screen When touching the area, even though the actual touch points are different, it is recognized in the same sensor channel, making it difficult to distinguish, including a tree-radiated sensor channel proposed to recognize a user's touch signal at a more accurate point. It is composed.
